It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are handled entirely through the x402 protocol on the Base L2 network.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee endpoint returns or what input it expects beyond a POST method. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation makes it difficult to know what data is actually served.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-response","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 data API","pay-per-request API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages are all effectively blank","No OpenAPI or JSON schema describing request parameters or response format","Unknown what fields or data the employee endpoint actually returns","Single hardcoded employee ID (36) in the URL — unclear if other IDs are supported or how to discover them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/36","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/employees/36","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt.
